The Massey Ferguson ignition key is used with the ignition switch of the MF 440 Xtra: it switches the tractor on and then starts it. A lost or bent key is enough to stop the machine, while a spare key costs little.<\/p>\n\n\n\n

Compatible models:<\/strong> Massey Ferguson 440 Xtra fitted with the 10300\/502 switch.<\/p>\n\n\n\n

Specifications:<\/strong> key with black plastic head, for the Valmy France ignition switch with the same part number.<\/p>\n\n\n\n

OEM part number:<\/strong> 10300\/502.<\/p>\n\n\n\n

Part sold under the Valmy France brand. If the lock itself is worn, replace the complete switch instead, supplied with its keys.<\/p>\n\n\n\n\n\n\n\n

Losing the tractor key in the middle of the season stops the whole job. A spare key kept in the workshop avoids that kind of stoppage for a few euros.<\/p>\n\n\n\n

Identifying your Massey Ferguson ignition key<\/h3>\n\n\n\n

This key matches the 10300\/502 ignition switch of the Massey Ferguson 440 Xtra. It has a black plastic head and a metal blade. To check, compare it with your current key, or send us a photo of the switch from the contact page<\/a>.<\/p>\n\n\n\n

Key only or complete switch<\/h3>\n\n\n\n

If the key turns smoothly in the lock, a spare key is enough. However, if the key forces, sticks or turns freely, the lock is worn: replace the complete ignition switch<\/a>, supplied with its keys.<\/p>\n\n\n\n

Why choose Valmy France<\/h3>\n\n\n\n

We work directly, with no middlemen, and we group small parts in the same shipment. See all our tractor electrical parts<\/a>.<\/p>\n\n\n\n

Ordering your ignition key<\/h3>\n\n\n\n

To receive a quote, give the part number, quantity and delivery country on the contact page<\/a>, or simply send a photo of the part via WhatsApp. We reply with the price, lead time and export documents required, and the shipment leaves from France or Spain. These parts are small and light: it is often wise to keep one in reserve, so a simple contact never stops the machine.<\/p>\n\n\n\n
